Description
Precision N Fixed Attenuator | 3 dB | 1 W | DC–18 GHz
The ROSNOL Precision N Fixed Attenuator, model FA-PCN1PCN25A-18G1W3/H33-H3, is designed for controlled RF signal attenuation in broadband 50-ohm systems operating from DC to 18 GHz. This attenuator provides a nominal attenuation value of 3 dB with a deviation of ±1.0 dB, supporting predictable signal level reduction across high-frequency ranges.Rated for an average power handling of 1 watt at 25 °C, the attenuator delivers stable electrical performance with a typical VSWR of ≤ 1.35. The precision N plug (male) to precision N jack (female) configuration uses a screw-on coupling mechanism, offering robust mechanical stability with a minimum of 500 mating cycles, a coupling nut retention force of ≥ 450 N, and an axial center contact captivation force of ≥ 28 N.
The FA-PCN1PCN25A-18G1W3/H33-H3 is constructed with gold-plated phosphor bronze center contacts, nickel-plated brass body components, and PTFE insulation. Manufactured under ISO 9001-certified processes, this attenuator is fully compliant with RoHS requirements.
